Site-to-Site VPN & Remote VPN Follow

Virtual private networks (VPNs) provide a way for secure connections to be established across the public network by tunneling the traffic. VPNs generally fall into two types — remote-access VPN and site-to-site VPN. Remote-access VPNs can be used to securely connect a host to a private network. For example, companies can allow staff to remotely access the file servers or other resources on the headquarters' intranet from an outside network using remote VPNs. With site-to-site VPNs, separate private networks could be joined for data sharing or other purposes. For example, private networks of different office branches of a company or even private networks of different companies can be joined.
